Under the Oak Tree
A shoujo manga that isn’t isekai! So FL is the runt of the litter, black sheep of her family that got married off due to political reasons. FL and ML get into an arranged marriage and after spending their wedding night together ML leaves for war and doesn’t return till 3 years later. 3 years have passed and ML returns as a war hero. It is said the Emperor wishes for the ML to divorce and marry the Princess instead. However, things aren’t quite they seem as the ML returns and is full of love and affection for the FL. FL is confused as she believed that the ML does not even like her. So onwards is their story together, which isn’t very exciting right now (chapter 28). - apparently this coincides with the novel at chapter 80. Also according to spoilers, there’s a lot of angst and drama ahead from the looks of the novel. https://forum.novelupdates.com/threads/under-the-oak-tree.97759/page-39#post-6084974
